UNITED STATES PATENT OFFIC JAMES FOGARTY, OF YORK, N. Y.

STEAM-PLOW.

SPECIFICATION forming part of Letters Patent No. 258,046, dated May 16, 18 82,

Application filed December 8, 18 81. (No model.)

To all whom it may concern:

Be itknown that I, JAMES H.FOGA.R'1Y, of New York city, iii the county and State of New York, have invented certain new and useful Improvements relating to Steam-Flows, of which the following is a specification.

I employ a revolving plow or agitator, carried on an upright shaft and rotated actively by steam-power apparatus mounted on a carriage, supported on wheels,with provisions for impelling the carriage at a moderate rate in .one direction or the other, guided by swiveling the wheels atone end." The framing is overhung at one side, so that the upright shaft and the plow or agitator, which revolves in a horizontal plane, cuts and pulverizes the earth in a channel of a width corresponding to the di ameter of the cutting instrument, and so that the whole of this channel is outside of the path traversed by the wheels. The machine is traversedalternatel y across the field and back withoutturning around, the wheels hearing all the While upon the firm or unplowed earth. I so arrange the parts that the weight of the framing, boiler, and machinery, as also of the fuel and water, is supported mainly on the driving.- wheels. The other wheels are preferably nearer together. They 'beara sufficient portion of the load to insure their efficiency as guiding means. I use a pair of smallcoupled engin'es, driving a shaft overhead which is geared very directly to the. plow-shaft, The engines may revolve continuously, and the plow turns in the same direction whether the carriage is traversed one way or the other. I gear with a relatively slow motion to the driving-wheels. The accompanying drawings form a part of this specification, and represent what I consider. the best meansof carrying out the invention. Figure 1 is a side'elevation, partly in section. Fig. 2 is a plan view. The remaining figures represent details on a larger scale. plan view'ofthe clutch device and connections. Fig. 4 is an elevation of the same. Fig. 5 is a section on theline war, seen in the direction of thearrows in'Fig. 3. Fig. 6 is a plan view of the plowor agitator.

' A is a substantial frame-work, forming the .body of the machine. It carries an upright boiler A with all the neeessar accom maiments'snioke-pipe, dampers, safety-valve, water-gage, &c.

The machine is adapted to work with equal facility in both directions; but, for convenience, I will designate as theforwagrd end that end which carries a pair of relatively-light wheels, 13, mounted on an axlc,b, swiveled by means of a train of mechanism operated by a hand-wheel to steer the machine. v

G G are driving-wheels mounted on an axle, 9, having ordinary provisions for making the wheels fast on the shaft, or setting them free by inserting pins through holes in the wheels and engaging with face-plates fast on the shaft, as has long been practiced in many such construclions.

A A indicate stout portion of the framing A, extending out on one side, and stiffly braced to support the plow-shaft.

V represents the revolving cutter or plowing device, and o the upright shaft thereof, which is supported in peculiar bearingsin the framing. A beveled gear-wheel, V, feathered on the upright shaft 0) of the revolving-plow device V, is engaged by a gear-wheel, O", keyed on the double-cranked shaft 0. The cranks of this shaft, which Isometimcs term the engine-shaft, or main shaft, receive connecting-rods from pistons working in cylinders m m, which are provided with the necessary valves,

worked by eccentrics on the shaft 0, constituting a small but complete and efficient double engine, receiving steam from the boiler,'A*, and communicating rotary motion to the main shaft 0 in the usual manner. The power expended on theplowViscomtnunieated through the gears O V. The small power required formovingthestructureis transmitted through a train of gearing, varied in its relations by a clutch, so that the engine and cutter may revolve uniformly in one direction, while the driving-wheels are at rest, or are being slowly turned in one direction or the other by the same engine.

A sliding clutch-piece, R, equipped with on dinary means, not represented, for imparting end motion, is feathered on a shaft, E, parallel to the main shaft 0. As the piece R is shifted one way or the other it engages with the corresponding clutch-faces of one of the two wheels E E which are mounted loosely on the shaft E. The wheel E engages with a gear-wheel, D which is keyed on a countershaft, D. Theother wheel, E, engages with a broad gear-wheel, G which is mounted on the main shaft 0. These shafts are so arranged that the broad geanwheel (Pengages also with a wheel, D, on the counter-shaft D. The shaft E engages, by means of a beveled-gear wheel, 12*, with a beveled-gear wheel, F, on a longitudinal shaft, F, which latter engages, by a beveled-gear wheel, F, with a beveled-gear wheel, G, on the axle g, and thus turns the large driving-wheels G G and moves the whole structure. When the clutch ltis movedin one direction it engages with the wheel E, and the engine-shaft (J acts, through the broad gear-wheel (J and the wheel E, to turn the shafts E, F, and g, and consequently the driving-wheels G,in one direction,and thus to move the machine in the direction which I have called forward. hen the clutch R is, on the contrary, moved in the opposite direction, it engages with the gear-wheel E, which reccivesmotioirnot directly from'the main shaft C, but through the interposition of the counter-shaft D, and the gear-wheels D and D This induces a reverse motion. It turns the shaft D in the same direction as the shaft E was before turned. It consequently, by the duplication of gears, turns the shaft E in the reverse direction and turns the shafts F and g, and consequently the connected driving-wheels G, in the direction to make the machine move backward. The machine is not required to turn around at the end of its course across a field, but the oblique movements required to shift its position laterally, and the proper guidance when it is on its course across a wide field, require that the steering-wheels B shall be capable of swiveling. This is effected through an upright shaft, H, carrying a worm-segment, H, which is engaged by an endless screw, 1,mounted on the shaft I, turned by the operator. The turning is effected by turning eitherof the hand-wheels by the fixed casing A".

ers'ing across a field and in shifting its position at the end of the course to act on a fresh breadth of earth on the return movement. If it be necessary,or desired in anyease, the machine may make two 'or more oblique movements at the end of each furrow.

The form of the framing and the arrangement of the parts causes but a small portion of the weight to rest on the steering-wheels B. Each of these wheels maybe loose on the shaft [1, and amoderate force applied through the hand-wheels J J is sufficient to turn the segment H, and consequently shift the position of the wheels B rapidly.

The boileris placed close to the axle g. The engine and gearing, as also the plow and its connections, rest their weight on the framing close to the boiler and near the driving-wheels G. The framing A is extended much beyond the axle g. The supply of fuel and of water is carried in that overhung end A. When the machine is light (by which I mean, when the water and fuel are nearly or quite consu med) some three-quarters of the weightrests on the driving-wheels G. When a full stock of coal and water is taken on a still larger proportion is carried on the driving-wheels.

I propose for soft alluvial soils, where this class of machine is most useful, to make the cutter or revolving plow V three feet in diameter, with a capacity for plowing twelve inches deep, or of being lifted to any extent up to eight inches clear. I propose for such machine cylinders nine inches in diameter, with- 'Babbitt metal, and forms a long and reliable bearing and a stiff support efficiently guided From the lower extremity of the telescopic bearing K a horizontal arm, K, projects. The piston-rod l is connected thereto, and when steam is admitted in the base of the lifting-cylinder L lifts the telescopic part K K, and with it the plow, as'will be obvious.

The provision for gaging the depth to which 'ily understood.

the plow V descends when the steam .is released from the piston may be the same as set forth in the patent of 1875 referred to.

When the steam has, by its tension on the piston-rod Z, acted through the arm K to lift the sleeve and plow the pressure of the steam need not be maintained to hold the parts elevated. This function is performed by alatch, 0, arranged to engage in recesses in the telescopic bearing K, and actuated by the lever-P turning on a fixed center, 19, and provided with a handle at each end, so that the latch can be disengaged by the attendant standing at either ofthe hand-wheels Jor J A spring,Q,'urges the lever into the position which engages the latch.

Rigid arms Z) extend forward from the front axle, b, and form supports for a transverse shaft, W, capable of being rocked either automatically or by the attendant. This shaft has rigidly fixed near each end a reversible scraper, W, adapted to remove any mud which may adhere to theperipheries of theforward wheels, B. It also has rigidly attached an arm, WF, carrying a weight, W which tends to hold it in one extreme position or the other. When the machine travels in one direction the earthy accumulations on the wheels are carried forward over the top of the wheels and removed by the scraper standing in the position shown in Fig. 8. Whenthe machine travels in the opposite direction the earth is carried up and is scraped off by the scrapers standing in the position indicated in Fig. 9. The change of position may be made by the attendant. It neglected by him, if a hard coating adheres to the wheels, the scrapers change their positions automatically. They do this by the force received from the motion of the hard mass acting on the back of the scraper, as will be read- The scrapers only require attention under unusual conditions.

Z is a removable cutter-wheel having a thin cutting-edge extending out beyond the periphery of one of the wheels B to which it is adjacent. It is confined on the extended end of the axle b by means of nuts or other suitable fastenings. Its function is to cut a thin score in the earth and take hold thereof to steady the front of the machine by guarding it against any motion laterally. This cutterwheel Z, equally with all the other parts, performs its functions successfully with the machine traversing in either direction. The mark in the earth made by the wheel Z is also useful as a guide in steering the machine on the next passage across the field. I provide two of the cutter-wheels Z, and extend, as described, both ends of the axle b; but it will usually be necessary to use but one. It can be used on either side. I prefer the side rep* resented.

Modifications may be made in theforms and proportions of many of the details, and obviously in the size of the entire structure. The breadths of the several wheels may be varied. The steering-wheels B will serve if quite narrow. One wheel of moderate width mounted on a swiveling support may serve.

A fIlGtlOll-CllltOh of any approved form may 0 beused instead of the positive clntchlt to en. gage the wheels E E alternately, as required.

Duplicate collars or any of the approved forms of thrust-bearings may be used to en.- gage the plow-shaft o with the telescopiebearing K.

Some of the advantages due to certain fea. tures of the invention may be separatelyenu= merated, as follows:

First, by reason of the upright shaft '0 and '80 plow V revolved, as shown, outside of thelinel of travel of the wheels, and of the capacity for reversing the motion of the carrying-wheels,

I am able to plow backward and forward across the field without turning around, and with all 8 the wheels resting on the firm and unp lowed portion while moving in both directions.

Second, by reason of the counter-shaft D, with its wheels D D mounted parallel to the shaft 0, with its broad gear-wheel (J in com- 0 bination with the other parts, as shown, I am able to transmit the power required for the slow traversing motion of the carriage in either direction at will by simply shifting the clutch It, while the plow V and its operating mechanism is'revolved always in the same direction.

Third, by reason of the arm K at the base of the telescopic part K, and of the pistonrod 1 and its connections arranged at the low level shown, I materially reduce the height of ICC the structure.

Fourth, by reason of the latch O, lever P, and spring Q, serving, as shown, relatively to he telescopic bearing K, shaft Q7, and plow V,

and its impellinggear-wheel V and its 0011- p05 nections, I am able to hold the plow elevated or depressed, and to release it efficiently and conveniently.

Fifth, byreason of the scrapers WV on the rocking shaft W, supported by the arms b no from the steering-axle b, provided with the loadedarm \N W, as shown, 1 am able to scrape the steering-wheels B efficiently whether traveling in one direction or the other, and

to insure the automatic adjustment of the 1 I 5 scraper for the motion of the machinein either direction.

Sixth, by reason of the cutter-wheel Z, arranged as shown, I am able to avoid the tendency of the machine to swing around in consequence of the resistance offered by the earth to the motion of the plow V.

I claim as my invention- 1. In a steam-plow having capacity for moving in both directions without turning around, the arrangement of the revolving plow V and upright shaft 1; outside of the line of travel of the wheels, as and for the purposes herein specified. 2. The revolving plow V, mounted on the 139 upright shaft 12, in combination with the engine-shaft G, with its gear-wheel G counter shaft D, with its wheels 1) D wheels E E clutch B, and shaft E, with its gear-wheel and the train of connections therefrom to the driving-wheels Gr, as herein specified.

3. In a steam-plow, the lifting-cylinder L and piston-rod l, arranged alongside the telescopic bearing K, and connected by the arm K, and adapted to serve relatively to each other and to the plow V, and its operating means, as herein specified.

4. In a steam'-plow,the latch O, lever I, and spring Q, in combination with the telescopic bearing K and the connected plow V 'v, as herein specified. V

5. In a steam-plow,the scrapers V,carried on a rocking-shaft, W, supported and loaded as shown, and serving relatively to the wheels 13, as herein specified.

6. In a plowing-machine, the driving-wheels G G, plowing device V, operated outside Of2o the path of the driving-wheels, and the cutterwheel Z, mounted at one end of the machine, combined and arranged as herein specified.

In testimony whereof I have hereunto setv my hand, at New York city, this 22d day of- 25 November, 1881, in the presence of two subscribing witnesses.
